Communication Network.
Answer: Communication Network is set of equipment or say
facilities that provide a communication services like to transfer of data
between two or more nodes located in any of its geographical point. Example of
such networks includes computer networks (LAN/WAN), telephone
2 Elaborate about TCP/IP Protocol
Architecture.
Answer: Two protocol architectures have served as the basis for
the development of interoperable communications standards: the TCP/IP protocol
suite and the Open Systems Interconnection (OSI) reference model. TCP/IP is the
most widely used interoperable architecture, and has won the "protocol
wars." Although some useful standards have been developed in the

Modulation (DM).
Answer: Delta Modulation (DM)
In delta
modulation, an analog input is approximated by a staircase function that moves
up or down by one quantization level ᵟ at each sampling interval (TS). An
example is shown in figure below, where the

Modulation (PCM).
Answer: Pulse Code Modulation
Pulse code
modulation (PCM) is based on the sampling theorem.
Sampling
Theorem: It states that “If a signal f(t) is sampled at regular intervals of
time and at a rate higher than twice the highest signal frequency, then the
samples contain all the information of the original

Do a detailed survey on destructor.
Answer: Destructors are usually used to deallocate memory and do other cleanup
for a class object and its class members when the object is destroyed. A destructor
is called for a class object when that object passes out of scope or is
explicitly deleted. A destructor is a member function with the same name as its
